I've successfully installed onto a USB drive, I've booted from the USB drive and got a menu with 4 options;
- Try Ubuntu without installing.
- Install Ubuntu.
- OEM Install (For manufacturers).
- Can't remember the 4th.
I selected the second - Install Ubuntu. Once I'd finished the installation it told me I needed to reboot in order to complete the installation. When I'd rebooted with the USB still in, it brings me back to the same menu with the 4 options. When I've rebooted without the USB, it boots Windows. Have I done something wrong?
